"The suspects approached the clerk and put a gun to his head, then struck the clerk in the back of his head knocking him to the ground," said Philadelphia Police Chief Inspector Scott Small. "AT this time the perpetrators then tied the wrists of the clerk behind his back with plastic zip ties and they proceeded to ransack behind the counter."

Small says the robbers then emptied the cash register, swiped a large amount of cigarettes and ran out of the store. In total, the men spent about 10 minutes in the store, the clerk told police.
